1.1 Running Octave

On most systems, Octave is started with the shell command ‘octave’.
This starts the graphical user interface (GUI). The central window in
the GUI is the Octave command-line interface. In this window Octave
displays an initial message and then a prompt indicating it is ready to
accept input. If you have chosen the traditional command-line interface
then only the command prompt appears in the same window that was running
a shell. In any case, you can immediately begin typing Octave commands.

If you get into trouble, you can usually interrupt Octave by typing
Control-C (written C-c for short). C-c gets
its name from the fact that you type it by holding down CTRL and
then pressing c. Doing this will normally return you to Octave’s
prompt.

To exit Octave, type quit or exit at the Octave prompt.

On systems that support job control, you can suspend Octave by sending
it a SIGTSTP signal, usually by typing C-z.
